SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 535,026, dated March 5, 1895. Application filed July 14, 1894. Serial No. 517.564. (No model.)

To all whom it may concern.-

Be it known that wai/*WILLIAM L. SEBRING and W'ILLIAM K. EDGAR, citizens of the United States, residing at Colorado Springs, in the county of El Paso and State of Colorado, have inventeda new and useful Seal-Lock, of which the following is a specification.

Our invention relates to seal locks, adapted particularly for use in fastening freight and other cars, and it has forits object to provide alock capable of use in connection with either a side or an end door; to provide means for securing the seal by the same looking pin which fastens the boltg-to provide means for holding the locking pin in its retracted position to prevent tampering by unauthorized persons; and finally, to simplify, improve and strengthenthe general construction of devices of this class whereby the cost of manufacture is reduced and the durability is increased.

Further objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings: Figure l is a perspective View of a lock constructed in accordance with our invention. Fig. 2 is a longitudinal section of the same, showing the bolt in its advanced or locking position. Fig. 3 is a similar View, showing the bolt in its retracted posi` tion. Fig. 4 is a detail view, in perspective, of the bolt. Fig. 5 is a similar View of the seal, reversed. Fig. G is a View of a tool employed in manipulating the lock.

Similar numerals of reference indicate corresponding parts in all the figures ofthe drawings.

l designates a swinging adapted to be attached in the ordinary or any preferred manner to a door, and 2 a staple adapted to be secured to the jamb or casing of the door for engagement with the eye 3 at the free end of the hasp, said parts forming or loose hasp,

unimportant features of the invention inasmuch as the lock, proper, Which is hereinafter described, may be used in connection With any hasp and staple having the general construction indicated.

A represents the casing of the lock, which is preferably formed of a single. casting or block of metal, and it is adapted to be secured to the framework of a car by means of the bolts 5. Formed longitudinally in this casing is a guide or Way G, in which fits the slidable bolt 7, adapted, When extended, as shown in Figs. l and 2, to engage the staple to hold the eye of the hasp in piace thereon. The nose or extremity of the bolt is slotted, as shown for the reception of an ordinary form of seal, (not shown,) when it is preferable to use the same, said slot 8 being beyond the staple when the bolt is in its extended position. f

Parallel with the above-described guide or Way is a seat or cavity 9, set in from the face or outer side of the casing, and adapted for the reception of a seal l0, an opening ll being formed in the face of the casing and com-'- muuicating with said seat or cavity, through which the outer surface of the seal may be seen. Said surface of the seal is adapted to be inscribed with the name of the company, the destination of the car, and other similar information which it is usual to apply tosuch devices.

Formed in the casing, perpendicular to the planes of the guide and the seat., is a transverse perforation 12 in which fits and operates the spring-actuated locking-pin 13, the perforation communicating With both the guide and the seat. The rear end of the locking-pin operates in a barrelple in which is arranged the coiled spring l5, bearing at one end against a shoulder 16 on the pin and at the other end against the partly closed end of the barrel. The reduced terminal 17 of the pin operates in an opening in the said partly closed rear end of the barrel to prevent lateral deflection of the pin.

The bolt is provided with an opening 18 which is adapted to register with the perforation l2 when the shoulder 19 of the bolt is in contact with the end of the casing, or in other Words when the bolt is extended, and the seal is provided in its reverse or inner side With a socket 20, also adapted Vto register with said perforation when the seal is in place, as shown in Fig. 2. When the locking-pin is repressed and the bolt is retracted the front end of said pin engages in a groove 2l formed longitudinally in the rear side of IOO the bolt, and while said parts remain in these relative positions the bolt is capable of alimited movement, controlled by the length of the groove.

Communicating with the groove, at each end, and extending through the bolt is a small perforation 22, through which, and the outer portion of the perforation l2, may be inserted a pin or thin instrument, such as that shown in Fig. 6, to repress the lockingpin sufficiently to disen gage it from the groove. This repression of the locking pin is designed to permit the forward movement of the bolt to bringits perforation 18 in alignment with the perforation 12, or the backward movement of the bolt to withdraw it from the casing.

The seal is preferably' constructed of wood or other opaque material which may be punctured by a sharp instrument but inasmuch as the end of the locking-pin cannot be seen its exact location must be known in order that the lock may be opened, hence its increased security. The end of the seal is beveled, as shown at 23, upon its inner side, to facilitate insertion when the locking-pin is extended.

The operation of the lock will be readily understood from the foregoing description, and it will be obvious that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages ofthe invention.

Having thus described our invention, we claiml. In a seal lock, the combination of a casing provided with a longitudinal bolt-guide, a parallel seat, and a transverse perforation intersecting said guide and seat, a bolt mounted to slide in the guide and having a transverse perforation to register with that in the casing, a seal fitting in the seat and provided in its rear side with a socket adapted to register with said transverse perforation, and a spring-actuated locking-pin fitting in the perforation in the casing, extending through the perforation in thebolt and engaging the socket in the seal, whereby the seal islocked in place solely by the pin which secures the bolt, substantially as described.

2. In a seal lock, the combination of a casing provided with a longitudinal bolt-guide, a parallel seat, and a transverse perforation intersecting said guide and seat, a bolt mounted to slide in the guide and provided with a transverse perforation to register with that in the casing and also with alongitudinal groove terminating in transverse openings which eX- tend through the bolt,aseal fitting in the seat and provided in its rear side with a socket adapted to register with the transverse perforation in the casing, and a spring-actuated locking-pin fitting in the perforation in the casing and adapted to extend through the perforation in the bolt and engage the socket in the seal, and also to engage the longitudinal groove in the bolt to limit the longitudinal movement of the latter, substantially as described.

In testimony that We claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
